President Obama and Prime Minister Benjamin Netanyahu of Israel offered radically divergent approaches to the perils of a nuclear-armed Iran on Monday even as they tried to cool down the personal nature of a long-distance dispute that has inflamed relations between the United States and Israel for more than a month.

No amount of uproar stopped him: Benjamin Netanyahu’s getting his speech to Congress. But he’s probably not going to get his way on the Iran nuclear deal that he’s going to spend Tuesday trying to take apart.

The fate of Obamacare rests with U.S. Supreme Court. Again. Three years after the court upheld the Affordable Care Act by a single vote, the justices are poised to consider a new challenge -- an appeal that has turned a routine question of how to interpret the statute into a threat to unravel the landmark 2010 law. The court hears arguments on March 4 and will rule by the end of June.
